SPECIFICATION forming part of Letters Patent No. 558,888, dated April21, 1896. Application filed November 26, 1894. Serial No. 529,925. (Nomodel.)

To aZZ whom it may concern:

Beitknown that we, ERASTUS E. WINKLEY and BENJAMIN PHILLIPS, citizens ofthe United States, and residents of Lynn, in the county of Essex andCommonwealth of Massachusetts, have invented a new and usefulImprovement in Sole-Leveling Machines, of which the following, taken inconnection with the accompanying drawings, is a specifica- IO tion.

Our invention relates to improvements in that class of levelinganachinesby which the operation of leveling is performed by a leveling-rollapplied under pressure to the sole of I 5 the shoe; and it consists of avibrating leveling-roll, a shoe supporting jack, and connectedmechanisms operating automatically to oscillate the vibrating roll overthe jack and change the relative lateral inclination of the roll andjack.

Our invention further consists of the devices and combination of deviceshereinafter set forth and claimed.

Our present application embraces a con- 2 5 struction indicated, but notdescribed in detail or specifically claimed, in Letters Patent of theUnited States No. 540,222, issued to us May 28, 1895, for the samesubject of illvention.

The object of our invention is to produce a machine of the above classwhereby the operation of leveling a shoe may be performed without manualinterference of the operator after the shoe is in position to be actedupon by the roll.

Our invention is illustrated by the drawings herewith submitted, inwhich- Figure 1 is a side view of a machine embodying our invention.Fig. 2 is a plan view.

0 Fig. 3 is an end view.

Similar letters and figures of reference refer to similar partsthroughout the several views.

Refering to the drawings, R represents the leveling roll, shown asconcave, but the form of which may be varied. As shown in the drawings,the roll R has a motion of vibration and also a traversing motion, whichcarries the vibrating roll over the jack longitudinally to bring theseveral parts of the sole upon which the roll R operates in contacttherewith.

13 represents the shoe supporting jack, which may be of any convenientform, such form being no part of our present invention. It may, however,conveniently consist of a heel-rest provided with the usual spindle anda toe-support with the usual form of toe-rest. The heel-rest may beconveniently arranged to move along the jack to or from the toe-supportto render the jack adjustable for shoes of varying lengths.

As shown in the drawings, the jack 13 has a single motionto wit, alaterally rocking or oscillating motion; but we consider that ourpresent invention, in view of other applications heretofore filed by usand now pending, embraces a reverse construction in which the roll R isrocked laterally, as shown in said applications, in which case it is tobe noted that the jack B is stationary, having no motion eitherlongitudinal or lateral.

To vibrate the roll R and oscillate the same (While vibrating)longitudinally over the jack, we find it convenient to provide thefollowing mechanism.

Mounted upon suitable ways 1 l on the frame A, which is a frame suitableto support the working parts of the machine, is a movable roll-carrierbed 2, free to reciprocate along the ways 1 1 toward and away from thejack B. In suitable bearings in the roll-carrier bed 2 is mounted aroll-carrier 3, free to tip in said bearings. The rollcarrier 3 mayconveniently consist of the fork a, in which the roll R is mounted insuitable bearings, and the rear portion 12, which is mounted in the bed2.

The fork a is secured to a rod 0, which extends through a sleeve cl orother suitable bearings on the rear portion 1), by which it is guidedand held in position and in which it is free to reciprocatelongitudinally. To prevent rotation of rod 0 in the bearing d the rod 0may be polygonal in section or provided with a feather or series offeathers engaging with feather-ways in the sleeve cl.

Mounted and free to rotate in suitable bearings in the roll-carrier bed2 is a shaft 4,

on which is an eccentric or crank 5, which is connected by a suitablepivoted connectingrod 6 with the rod 0. The shaft 4 may be convenientlydriven by a belt 7 on the pulley 8, and the arrangement is such that therotation of the shaft reciprocates the rod 0 and vibrates the fork a andthe roll R mounted therein. Provision is made for the tipping motion ofthe roll-carrier 3 by mounting the shaft 4 on the roll-carrier bed 2with its axis of rotation coincident with the tipping axis of theroll-carrier, and provision is made for the reciprocation of theroll-carrier bed 2, as hereinafter described, by connecting the belt 7with a swinging pulley 9, which allows such reciprocation without unduechange in the tension of belt 7. As shown in the drawin gs, the pulley 9is supported laterally by an arm 10, mounted on the power-shaft 11 andfree to turn thereon, and vertically by an arm 12, mounted and free toturn on the shaft 4. The arms and 12 are pivotally connected by thetrunnion 13, which supports the pulley 9. The same result may, however,be accomplished by several other well-known devices.

The roll-carrier bed 2 is reciprocated along the ways 1 1 by thefollowing mechanism: Mounted and free to rotate in suitable bear ings inthe frame A is a shaft 14, which carries rigidly secured thereto androtating therewith a wheel D. In the wheel I) is formed the cam-path 15,in which works a cam-roll 16, carried by a swinging lever 17, which isconvenientlymounted upon a shaft 18, having suitable bearings in frameA. The swinging lever 17 is connected by the connecting'rod 19 with theswinging lever 20, conveniently mounted upon the shaft 21, havin gsuitable bearings in frame A. The swin ging lever 20 is connected by thelink 22 with the roll-carrier bed 2, the arrangement being such that therotation of the wheel D effects an oscillation of the lever 17, and, bymeans of the connecting'rod 19, of the lever 20,which, by the link 22,imparts areeiprocating motion to the roll-carrier bed 2 along the ways1 1. The lever 20 is provided with a circular adjustment-way 23, alongwhich the connecting-rod 19 may be moved to vary the length of theoscillation of lever 20, as above described, and consequently thedistance over which the roll-carrier bed is reciprocated. Pressure issecured upon the roll-carrier 3 by a suitably-placed spring or series ofsprings 25, preferably secured to the roll-carrier, and a bracket 26 onthe roll-carrier bed 2. The downward action of the spring is limited bya bracket 27, also conveniently secured to bed 2 and bearing againstroll-carrier 3. As shown in the drawings, the rollcarrier 3 rests upon athreaded bolt 28, provided with suitable threaded bearings in thebracket 27, which renders the limit of the downward motion of theroll-carrier 3 adj ustable.

To secure the laterally rocking motion of the jack hereinbeforesuggested we have provided the following as a simple and convenientdevice: On the opposite face of wheel D is formed a second cam-path 30,in which works the cam-roll 31, carried by a swinging lever 32, suitablymounted in the frame A, (conveniently upon a shaft 33, having suitablebearings in frame A.) The jack B is provided with suitable trunnionshaving bearings in the uprights or standards 34 34 on the frame A, inwhich they are free to rock, the arrangement being such that the jack Bis free to rock laterally thereon and is supported thereby in the frameA.

To one of the trunnions supporting jack 1? is rigidly secured an arm orlever 35, which is connected by the connecting-rod 36 with the swinginglever 32, the arrangement being such that the rotation of the wheel Doscillates the lever 32, and by means of the connecting-rod 36 and lever35 laterally rocks the jack B. The arm 35 is provided with a circular adjustment-way 37, along which rod 36 may be moved to adjust the lengthsof the lateral rock or oscillations of the jack. The campaths 15 and 30are so formed and timed with reference to each other that the lateralrocking motion of the jack and the traversing or oscillating movement ofthe roll cooperate with each other to present the several parts of thesole (requiring to be leveled) to the vibrating roll in the properposition to receive its operation.

The wheel .D may be conveniently rotated by means of a worm-gear 40,keyed or otherwise rigidly secured to the shaft 14. The gear 40 isdriven by a worm 41, carried by the shaft 42, mounted and free to rotatein suitable bearings in the frame A.

The shaft 42 may be driven by a belt on the pulley 43.

The form and arrangement of the cam-paths 15 and 30 are such that theoperation of levelin g a shoe is performed during a single revolution ofthe wheel D. This arrangement is not essential and may be varied torequire more or less than a single revolution.

A stop mechanism is provided and arranged to stop the revolution of thewheel D when the operation of leveling is completed. As several commonforms of mechanism of this nature can be readily adapted to secure theabove-suggested result, we do not consider a detail description thereofnecessary herein. The form shown in the drawings consists of a clutch ofany suitable form, which when in engagement rotates shaft 42 with pulley43, but when open allows the pulley 43 to rotate independently of shaft42. In frame A is mounted a rod 51, free to slide and also to retate insuitable bearings. The rod 51 is connected with clutch 50, and asuitably-placed spring 52 acts to push the rod forward (toward front ofmachine) and keep the clutch in engagement. The rod 51 carries ashoulder 53 in the path of a dog 54 on the gear 40, and

ICO

when the gear l0 has made a revolution the dog 54 strikes the shoulder53 and, moving back rod 51, opens clutch 50.

To start the machine the operator presses down on the treadle 55 carriedby rod 51, and thereby rotates the rod 51, turning the shoulder 53 outof the path of dog 54, when the clutch is closed by spring 52. Whenreleased, the treadle is returned to its original position and shoulder53 again brought in path of dog 54c by a suitably-placed spring (notshown) attached to the treadle.

To use our improved leveler the operator places a shoe upon the jack,adjusts the several mechanisms according to the size and shape desiredto be given to the bottom of the sole, presses down upon the treadle tostart the machine, and (power being applied) the operation of levelingis performed and the ma chine stops for the removal of finished Workwithout further interference on the part of the operator.

\Ve do not consider our invention limited to the form and arrangement ofmechanisms herein shown and described; but

lVe claim, broadly, and desire to secure by Letters Patent-'- 1. In asole-leveling machine the combination of a shoe-supporting jack, avibrating leveling-roll capable of a longitudinally-traversing movementwith reference to the jack, and connected mechanisms operatingautomatically to change the relative lateral inclination of the roll andjack and impart to the roll a longitudinally-traversing movement withreference to the jack substantially as described.

In a sole-leveling machine the combination of a shoe-supporting jackcapable of being rocked laterally, a vibrating leveling-roll capable ofa longitudinally-traversingmovement with reference to the jack,andconnected mechanisms operating automatically to laterally rock the jackand impart to the roll a longitudinally-traversing movement withreference to the jack, substantially as described.

3. In a sole-leveling machine the combination of alongitudinally-reciprocatin g roll-carrier bed, a roll-carrier on saidbed, a vibrating leveling-roll mounted in the roll-carrier, ashoe-supporting jack, and connected mechanisms operating automaticallyto reciprocate the roll-carrier bed and to change the relative lateralinclination of the roll and jack, substantially as described.
